Small but Mighty: Selected Commensal Bacterial Species Determine the Effectiveness of Anti-cancer Immunotherapies

Immunity. 2015 Dec 15;43(6):1037-9. doi: 10.1016/j.immuni.2015.11.014.

Abstract

Commensal microorganisms influence malignant progression by altering systemic inflammation. New data from two groups (Vétizou et al., 2015; Sivan et al., 2015) indicate that the abundance of specific commensal bacterial species enhances the anti-cancer activity of immune checkpoint inhibitors.
